Vein puncture device and system and vein puncture control method

Abstract

The invention provides a vein puncture device and system and a vein puncture control method. The system comprises a control device and a vein puncture device; the vein puncture device and an ultrasonic probe are connected to the control device respectively; the vein puncture device is used for collecting data information of a preselected target vessel through the ultrasonic probe, and sending the data information to the control device; the control device is used for calculating position information of the target vessel according to the data information, and generating a control signal according to the position information; the vein puncture device is further used for controlling a needle body to be punctured and a hosepipe to be embedded which are fixed on the vein puncture device itself to puncture skin according to the control signal. The vein puncture device and system are low in overall manufacturing cost compared with a robot medical system, can automatically control the vein puncture device to conduct motions of needle inserting, hosepipe embedding and needle withdrawing, reduce the labor intensity of an operator, are high in locating precision coordinated with the ultrasonic probe and under the guidance of the ultrasonic probe, can achieve one-hand operation, are low in experience requirement of the operator, and can adapt to the dynamic environment.

Description

technical field [0001] The present invention relates to the technical field of automatic catheterization, in particular to a venipuncture device, a system and a venipuncture control method. Background technique [0002] Venipuncture is a medical nursing method to alleviate the patient's pain of repeated puncture and facilitate long-term infusion. Venipuncture can effectively avoid the pain caused by repeated puncture of superficial veins, and it can also effectively avoid the damage of antitumor drugs to blood vessels and local tissue necrosis caused by drug extravasation. The key points affecting the development of venipuncture catheterization technology are the puncture guiding device and the control of the puncture needle movement. Compared with manual operation, the auxiliary medical robot using mechanical force has high accuracy and stability, and can reduce the labor intensity of the operator. Therefore, in order to perform soft tissue puncture surgery stably and acc...

Problems solved by technology

[0003] However, due to factors such as the high cost of robots, the complicated calibration and matching methods of robots and patients, and the overly specialized operation of robots, it is still difficult for robot-assisted puncture to reach the level of widespread application.
